I SPECIFICATION forming part of Letters Patent No. 522,638, dated July 10, 1894;

Application filed March 28, 1894- To all whom it may concern.-

Be it known that I, ALLIE R. WELCH, a citizen of the United States, residing at Chelsea, in the county of Washtenaw and State of Michigan, have invented certain new and useful' Improvements in Ovens, of which the following is a specification, reference being had therein tothe accompanying drawings.

The invention consists in the peculiar con-' struction of the bottom plate of the oven, whereby the bottom plate may be adjusted to any size stove, and further in the peculiar construction, arrangement and combination after described.

In the drawings, Figure 1 is a perspective view of an oven showing my improvement applied thereto. Fig. 2 is a side elevation showing the oven as in use upon a stove. Fig.3 is a section on line a as Fig. 1. Fig. 4 isa section on y y Fig. 1. Fig. 5 is a cross section on line 2 2 Fig. 2, showing a top plan View of the bottom plate illustrating a modified form.

In the manufacture of oil stoves it has been found necessary to manufacture for each size of stove, (for instance of the type shown in Fig. 2,) a separate oven which will fit that stove, that is, having the proper opening in the bottom plate.

My invention enables me to manufacture the bottom plates of all the ovens alike and to adjust the opening in the bottom plate to fit any one of a number of sizes of stoves, thereby greatly simplifying the manufacture, and at the same time increasing the'efficiency of the oven, by having-it properly adjusted to the stove upon which it is intended to be used.

A is the oven proper of any desired construction, and B is the bottom plate thereof having a central aperture, preferably rectangular. On the bottom plate, preferably exteriorly thereof, I arrange guide strips 0, preferably of sheet metal, bent into substantially G shape. as shown, and in the guides thus formed I. arrange wings D, one on each side, having their edges sliding in theguides so described.

that they may be adjusted to or from each other. These wings I provide on their inner edges with the upturned lip E, which acts as a stop against the edge of the bottom plate, as shown in Fig. 3, to prevent the accidental disengagement of the wings from the bottom plate. The opposite edge of the wings I bend inwardly to form the spring flangesFbearing against the bottom plate and serving to hold the wings in any adjusted position.

G is a rib or flange formed about midway the width of the wings, preferably by crimping the metal, as shown in Fig. 3.

The parts being thus constructed it is evident that the wings maybe adjusted to or from each other over the opening in the bottom of the plate, so as to fit upon the top of any stove, the flanges G being brought in such proximity to the side of the stove as to engage therewith,as shown in Fig. 2, and the spring flanges F serving to hold the wings in their adjusted position If it is desired to adjust the aperture in the bottom plate both as to length as well as width I may arrange corresponding wings H on the inner face of the bottom plate, as shown in Fig. 5, by simply forming suitable guide ways H along the ends of the aperture and engaging these wings therein. In this case I preferably form simply a central stop I, so as not to interfere with the adjustment of the side wings.

What I claim as my invention isl. Inv an oven, the combination with the apertured bottom plate, of adjustable side wings slidingly engagingon the bottom plate, substantially as described. I
